The invention relates to the technical field of vehicle control, and particularly discloses a traction seat unlocking control method and system and a traction trailer. The traction seat unlocking control method comprises the steps that the working state of a hand brake in the traction trailer is judged; when the hand brake is in the pull-up state, a gas path of a mechanical gas valve is conducted, and meanwhile whether an operation switch is pressed down or not is judged; when the operation switch is pressed down, the electromagnetic gas valve is driven to be powered on so as to conduct the gas path, and gas in the gas storage cylinder is led into the unlocking air cylinder so that the traction base can be unlocked. By means of the mechanical air valve and the electromagnetic air valve which are connected in series, air in the air storage cylinder can be introduced into the unlocking air cylinder to unlock the traction base only when the electromagnetic air valve and the mechanical air valve are both conducted, the possibility that the traction base is unlocked unexpectedly due to misoperation of a driver is greatly reduced, and the accident risk that the trailer is out of control during driving is avoided.
本发明涉及车辆控制技术领域,具体公开了一种牵引座解锁控制方法、系统和牵引挂车。该牵引座解锁控制方法包括:判断所述牵引挂车中手刹的工作状态;在所述手刹处于拉起状态时,导通机械气阀的气路,同时判断操作开关是否按下;在所述操作开关按下时,驱动电磁气阀通电以导通气路,将储气筒中的气体通入解锁气缸以进行牵引座解锁。通过串联设置的机械气阀和电磁气阀,在电磁气阀和机械气阀均导通时才会将储气筒中的气体通入解锁气缸以解锁牵引座,极大的降低了司机因为误操作而导致牵引座非预期解锁的可能性,避免行车中挂车拖挂失控的事故风险。
